Application filed April 7,-

To' 'all @whom t may concern Be it known that I, CHARLES M. KEMPER, a citizen of the United States, residing at )Kansas Cit ,in the county of* Jackson and State lof issouri,'have invented a certain new fand useful improvement in Car-Door Mechanisms, *of which the following is a -My invention relates to improvements in v'ca'rdoor mechanisms. v

.It relates particularly to doors for grain cars.

A further object vof my invention is to provide novel 'means for sealing the edges .of the door when the latter is closed.

'Still another novel feature of my invention is the provision of novel means for retaining the door in proper vertical alinement when in the closed position.

A further object of my invention is to provide a mechanism of the kind described which is simple, cheap to make, which is strong and durable and not liable to get out of Order. Y

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings, which illustrate the preferred embodiment of my invention,

Fig. 1 is an elevationof a portion of a ca'r body provided with my improved mechanism, portions being broken away.

Fig. 2 is a horizontal section on the line 2 2 of Fig. 1.

Fig.` 3 is an enlarged vertical sectional view on the line 3 3 of Fig. 1.

Fig. 4 is an enlarged horizontal section on the line 4 4 of Fig. 1.

Fig. 5 is an enlarged vertical sectional view on the line 5 5 of Fig. 1.

Fig. 6 is a vertical sectional vview on the line 6 6 of Fig. 4.

Fig. 7 is a horizontal sectional view, enlarged, on the line 7 7 of Fig. 1.

Similar reference characters designate similar parts in the dilferent views.

1 designates a car body provided with a side doorway having jambs 2 and 3.

Attached to the inner side of the jamb 3 is a vertical channel plate 4, between the flanges of which the j amb 3 is located, and the outer flange of which is wedge-shaped and spaced apart from the outer side of the jamb 3 and which forms a seat for sealing the adjacent vertical edge portion of a main door 5, which is supported at its upper end 1922. Serial N`0. 553,418.

Vdoor v5 has fitted over it a vertical channel shaped plate 9, Figs. 2 and 7, the inner flange of which Ahas a portion spaced apart vfrom the inner side ofthe door. verse bolts 10 ext-end through the door and Transthrough the flanges V of the channel plate 9. Respectively mounted on the inner ones ci 'said bolts 10 are spacing rings 11 adapted to respectively enter notches 12, `provided in the vertical edge-of the outer flange of the channel plate 4. TheV innen flange of the plate 9, when the door is closed,'engages the inner side of the wedge-shaped outer flange of the channelV plate 4, and draws the door tightly against said flange.

. The left vertical edge'portion of the door 5 is provided with a vertical plate 13, doubled upon itself and embracing the inner and outer sides of the door. The doubled portion of the plate 13"'is adapted to enter lbetween a vertical angle plate 14Vattachedto the jamb 2and`an angle plate 15 also secured to the jamb and having a portion spaced apart from the 4plate 14, Fig. 4, thus forminga seat to rcreive the plate 13 when the door is closed. Extending through the plates 15 and 1 4 and into the jamb 2 are horizontal bolts 16, on which are respectively mounted spacing rings '17 adapted to respectively enter notches 18 which are provided in the vertical edge of the plate 13.

The rings` 17 and 11 serve to hold the door in vertical alinement when the door is in the closed position. rIhe notches 12 and 18 are preferably inwardly converging, so as to engage and guide the rings 11 and 17 respectively.

For forcing the door 5 to and from the closed position, it has secured to it one end of a horizontal rack bar 19 provided in its upper edge with teeth 2O adapted to be engaged by a double acting pawl 21 pivoted to an upright lever 22, which is pivoted by a horizontal bolt 23 to the car body 1.

Vhen the pawl is in the position shown in solid lines in Fig. 1, and the lever is oscillated, the rack bar 19 and door 5 will be forced to the closed position. By disposing the pawl 21 in the position shown in dotted lines in Fig. 1, and oscillating the lever 22, the door is forced to the open position. For guiding the end of the rack bar 19 which is distant from the door 5, there may be rotatably'inounted on the outside of the body 1, in a housing 24 secured to the body, a roller 25 which supports the lower edge of the raclr bar 19.

' The door 5 may be pro-vided with an auxiliary door 26 hinged thereto. For locking the door 26 and the door 5 in the closed position with the use of but a single locking pin, there is provided a hasp 27, pivoted 'by a horizontal bolt 28 to the outside of the door 5 and which is adapted to receive therethrough at its lower end a staple 29 secured to the door 5 at the outside thereof. When so engaged, the upper end of the hasp 27 engages the outside of the auxiliary door 26. A hasp 30 is pivoted to the jamb 2 by a staple 31 and is adapted to receive therethrough and to lockingly engage the staple 29 at the inner side of the hasp 27. A pin 32 is adapted to be removably fitted in the staple 31 at the outer side of the hasp 27 The pin 32 may be sealed in the usual manner by a wire 33 extending through the pin and engaged by a lead seal 34, Figs. 1 and 3.

To open the door 5, the seal 34 and wire 33 are removed from the pin 32, after which the pin is removed from the staple 29, following which the hasps 27 and 30 are disengaged from the staple 29. The pawl 21 is then moved to the position shown in dotted lines in Fig. 1. Upon oscillating the lever 22, the rack bar 19 and the door 5 will be forced to the o-pen position.

Upon swinging the pawl 21 to the position shown in solid lines in Figs. 1 and 2, the door 5 will be forced to the closed position, shown in Figs. 1 and 2, and in 4 and 7, at which time the plate 9 will engage the outer wedge-shaped flange of the plate 4, thus drawing the door 5 tightly against the latter, and the plate 13 will fit tightly between the plates 14 and 15, and the inside lower portion of the door will also fit tightly against the body of the car.

I do notv limit my invention to the structure shown and described, as many modilications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is y- 1. In a car door mechanism, a car body having a door jamb, twovertical plates, fixed spacing rings between said plates, the inner plate beino attached to said jamb, bolts extending through said plates and respectively through said rings for attaching said plates to said jamb. and a door slidable on said body and having a vertical edge portion adapted to enter and fit snugly between said plates, said edge portion having notches adapted to respectively receive said rings when the door is closed, substantially as set forth.

2. In a car door mechanism, a car body having a door amb, a vertical plate secured to said liamb and having a vertical flange provided with notches, a door slidable on said body, a vertical plate secured to the inner side of said door adapted, when the door is closed, to engage the inner side of said flange, and members fixed between the last named plate and said door adapted to enter said notches respectively when the door is closed, substantially as set forth.

In testimony whereof I have signed my name to this specification.

CHARLES M. KEMPER.
